QUICK-DETACHABLE APPLIANCE.

Application inea rebriiary 2o, 1926. serial No. 89,712.

This invention relates to the class of appliances capable of being quickly, easily and effectively applied to a quickly and easily detached from such element. i l

One object of the present invention is to provide an appliance which may be quickly and easily applied to a threaded vtire valve stem extending through a radial bore in the rim of a vehicle wheel to effectively hold the valve stem inl place against withdrawal radially outward through said bore, and to support the stem in axial alignment in said bore out of contact with the wall of said bore, the said appliance also beingquickly and easily detached.

Another object of the invention is the provision of an appliance capable of being quickly and easily applied to a valve stem approximately at the point atwhich binding action is set up which will be capable of threading adjustment to finally and effectively set u the binding action against portions of tfie rim of av vehicle wheel through which the stem extends, and which may be quickly detached without requiring unscrewing of the appliance.

The nature'of the invention and its dis-- advantages willtinguishing features and appear when the 'following specification is read in connection with the accompanying drawing, in whichr f Figure 1 is a transverse sectional view through the rim of a vehicle wheel with a portion of a pneumatic tire structure including the usual valve stem extending through said rim with the appliance of the present invention effectively employed.

The appliance of the present invention isv capable of a wide range of application. In

p the present instance the appliance is shown in use in connection with a threaded vvalve stem 10 of a pneumatic tire structure, a portion of which is shown at 11, as being supported on the usual demountable rim 12 arranged Von the felly or 4rim 13 of a vehicle Wheel. The said valve stem as is usual extends through aradial bore, such as the bore 14 inthe fellyl 18. Thebore 14 is somewhat larger in diameter than the valve stem 10 to permit the same to be readily extended therethrough. A tire valve stem is comparatively long in order. `that it may extend through the'felly of the wheel to accommodate the dust cap. Different types of binding nuts have been employed in conjunction with the valve stem to hold rthe same in These types of binding nuts require their being threaded all the way from the `free end of the valve stem to the point at which binding action with the felly is set up. In some cases the valve stem is provided with flat sides to accommodate nuts having mutilated vthreads to effect a quick application and a quick detachment. i

The form of appliance 15 shown in Figs. 1l to 6 is capable of application at a point in the length of the valve stem for threading adjustment, which will only require one or two turns of the appliance to set up a binding action, and which can be readily detached from the valve stem `without unscrewing the same. Referring now more particularly to the views of the drawing mentioned,

yit will be apparent that, the appliance comprises an element16 and an element 17. The element 16 is produced from a. single piece of material which is cut and formed toI provide members 18 which are connected together as circular portion 2 0, each of Awhich has threads 21 on the inside thereof. kNormally the members 18 bear such a relationship with respect to eachother as to dispose the semin at 19, and flexibly related to eachv "other, Each of the members 18 has a semicircular' portions 2O spaced apart tc accommodate therebetween thevalve stemvvlO, but

semi-circular p0rthreads of the valve stem 10.l Each of the semi- :circular portions 2O is chamfered or beveled as at22` for a purpose to appear. lllach of 20 are separatedsuiliciently.to accommodate the semi-circular portions 20 is rounded as at` 23. rlhe retaining member 17, in 'the present instance, is made trom a single piece of ma terial, and is cutandformed to provide 'ana'- anniilus 24 and Wings or extensions 25 on the annulus 24 and disposed vChainet-rically opfposite each other. @ne of the Wings 25 is divided to provide spacedinoinbers 26. The retaining element 17 is pivotally connected to the element'16, andV this accomi'ilished by the employment oi a pivot pin 27 or the like which extends 'through 4the members 26 and tliestraight portions ot the connected members 1S which aredisposed between 'the members 26. ln order to limit the movement ot one of the elements 16 and l17 With re spect to 'the other, Athere is 'provided a pin and'slot connection, a slot 28 is put into each of the straightV portions oi the niembers 18, and a pin 29 is su'iported by the members 26 and cxteinlsA through theV slots 28.

llllhen the' element 16, Which may be aptly termed a nut element, is in the position shown in .Fig..3, the seii'ii-circular portions the 'valve stein 10 therebetween. lnA this Way the 'appliance is arrangedon the valv stein" approximately at a point at which 'a' binding action is to be set up. be done quickly and easily due to the 'tact that 'the threads' of the seini-circular portions and the threadsof the valve stem semicir'cular portions 20 to be flexed toward each other due tothe tact that their rounded portions; 23 Will. ride onthe inner Walls of, the annulus 24. vthe retaining element `17 causes the scmif This relative movement olE ciicular portions A2O to embrace the valve stem With the threads of the semi-circular portions n'iutually engaged with the threads of the valve stem 10 for threading adjust ment on the latter. `rIhe .threadingIadjustment is accomplished by manipulating the Wings until an effective binding action is set up.A In this manner tlievalve stem 10 `Suhicient trictional contact is set is'sec'urely held in place against radial outward' movenienhxand is also` maintained in axial alignment in the bore 14, and prevented from rubbing against the Walls of the bore. This is true because ot the tact that the beveled portions 22 enter the boi'e 14 as shown most Aelearl in Fig. 1 While the annulus 24V impinges against the telly 13.

the annulus 24 and the semi-circular portions 20 to hold the element 17 against movement, and it therefore `maintains the semi- 'it is onlyznecessary Yto svvingthelelement 17 This mayon its pivot, ,Whereuponthe semi-circular portions 2() will flex avvay from each other and therefore permit the appliance to be detached: since the threads of the semi-circular portions 2() will be disengaged `from the threadsof'ifthe valve stem 10. Thus theappira-nce is removed Without unscreiving'the same.`

ln the form of the invention shown in 7and 8, theapphance 30villustrated comprises*anuelement 31 'the equivalent ot Athe element 160il the other form ofthe appliance, and a retaining element 32,l the equivalent of the retaining element '17 of the other form of the'appnance. rllhe elexment 31 comprises a member 33 and a member 34.' The member 33y comprises a semicircular portion having threads 36, and Wings 37. One oi' the'r Wings is provided with anapertured terminal l'lhe meme ber 34 is substantially similar to the memi'urcations to receive a ein 43-to'ettect a pivotal connection of' the members 33' and 34. It Will therefore be'understoodlthat the members 33 and 34,1nay be moved toward and away from each other. l/Vhen the members 33 andy 34 "are brought together as shovvn in Fig. 7, the `semicircular portions 35` and 39 constitute a n ut.y The semi-circular portions/35 and 39 are maintained in the `nut forming relationsliipyby the retaining element 32. The retaining` element 32 is stamped, bent and formed from a single piece of material to provideside portions 44 andy 45V Wliichare connected together by a portion 46, the latter providing a manipulating end 47, A'pivoted pin 48^Which passes through the side portionr 44 and which extends l'int-o the'iving 41 ot' the member 33 constitutes a pivotal connection olithe element 32 to the member A'-'illheside portion 45' of the element-32 iscut as at 49at an angle sothat'wvhentheE element132 is swung to an inactive posit-ion the members 33and 34 can have pivotal movement to be either brought together-or separated.

2F rom the foregoing itA Will be apparent that the appliance 30 can be pnt -into use substantially similar to rthe-manner in Which Y the appliance 15 .isfput into use. The app1 up betweenv -Y ance 3() may be quickly applied tothe valve vst em by swinging the element r42-to the poition shown in dotted lines in Fig. 8, Whereupon the members 33iand- 34 may be. separated and then brought together to mutually engage the threads 36 and 40.1respectively of-ithe portions 35 and 39 With the ythreads of the valve'stem. The :retaining element 32 is then moved to an active position to."

maintain the nut forming relationship of the portions 35 and 39. By turning the appliance in this condition 1t may be adjusted on the stem to set up the desired binding; act-ion.

I claim: y

l. An appliance comprising an element split to provide l'ieXibly related members having semi-circular` threaded portions which may be brought together in coacting relationship to form a nut for threading adjustment on a threaded element, and means pivoted on said split element and adapted to embrace and to exert pressure on both of said members when moved into the plane ont' said members, to maintain them in the coacting` relationship, said vmeans being movable on its pivot to a position to permit said members to flex their threaded portions out ot threading' engagement with said threaded element, so that the appliance maybe quickly moved endivise off the threaded element.
